WILLIAM L. PAUL, OF SOUTH BEND, INDIANA, ASSIGNOR TO OLIVER OHILLED PLOWWORKS,

V OF SOUTH BEND, INDIANA.

PLOW s'rnuo'runn.

To all whom it may concern:

Be it known that I, WILLIAM L. PAUL, of South Bend, in the county of St.Joseph and State of Indiana, have invented certain new and usefulImprovements in Plow Structures; and I do hereby declare the followingto be a full, clear, tion of the invention, such as will enable othersskilled in the art to which'it appertains to make and use the same.

My invention relates to a plow structure adaptable for use in theconstruction of what are commonly known in the art as listers.Heretofore, in machines of this type the frame has been made to extendforwardly to provide a stop. for holding down the front end of the beamwhen the plow is raised, the latter being necessarily pivoted forward ofthe center of gravity.

One object of my invention is to so build.

a plow structure that the frame, can be made to terminate at the axle;thus permitting of a light and attractive construction, and to provide aforwardly projecting bail which will serve the oflice ferred to.

A further-object is to provide simple and efi'icient means whereby aspring can be employed to assist in raising the plow and also inshortening up the machine as the plow is raised. v

\Vith these object in view the invention consists in certain novelfeatures of construction and combinations of parts as will hereafter bedescribed and pointed out in the claims. i

In the accompanying drawings, Figure 1 is a side elevation, partly insection, of a machine embodying my improvements. Fig. 2 is a plan viewof the same.

1 represents an arch-axle mounted at its respective ends within the hubsof carryingwheels 2. At the juncture of the U-shaped intermediateportion with the horizontal portions of the arch-axle, brackets 8 areattached, and to these brackets the respective members of the machineframe 4 are pivotally connected. The frame t is of general V-shape andat the rear meeting ends" of its members a bracket 5 is secured toafford a bearing for the vertical upper portion of an axle 6, the lowerportion of said axle being bent rearwardly and provided at its lower endwith laterally projecting inclined jour- Specification of LettersPatent.

ceive the forward, intermediate portion of a bail 13, the rear ends ofwhich are con nected with the brackets 3 on the arch-axle.

As before stated the frames of planters of the type to which myinvention relates have been made to extend forward to provide a stop tohold down the front end of the beam when the plow is raised, thusnecessitating the pivoting of the plow forwardly of the center ofgravity. avoided in my machine and the bail 13 is made to serve thepurpose of such a stop and furthermore I am enabled to shorten themachine-by terminating the frame at the axle.

Bracket 14-, secured to the frame 4, is provided with a toothed-segment15 and affords a bearing for the pivot pin 16 of a lever 17, said leverbeing provided with a latch 18 to engage the toothed-segment 15. An arm19 is secured to the pivot pin 16 and is connected, by means of a link20, with a bracket 21 secured to the arch-axle. It is apparent that bythe operation of this lever the plow beam and the plow carried therebycan be raised and lowered. To assist in the raising of the plow a spring22 may be employed. connected with the frame 4 and the other end withthe arch-axle.

The upper end of the axle 6 on which the follower-wheels 8 are mounted,is provided with a notched-segment 23 and with this segment a latchv 24:mounted on the frame 4, is adapted to engage to retain thefollowerwheels in their normal position. A rod 25 is attached at itsrear end to the latch 24 and connected at its forward end with abell-crank lever 26 through the medium of a link 27 said bell-cranklever being at tached to the pivot- By means of this construction, whenthe lever 17 is operated to raise the plow, one arm of the bell-cranklever 26 will be engaged by the lug 28 on the arm 19 and operate,through the medium of the rod 25 Such construction is pin 16 of thelever 17. r

to withdraw the latch 2% and release the'axle 6, thus permitting thelatter to turn.

Supports 42 are secured to the frame f for the accommodation of a seat43 and footrests at are provided at the depending ends of a yoke 4:5secured to said frame.

The details of construction may be varied without departing from thescope of my invention and hence I do not wish to be restricted to theprecise constructive details herein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is-

1. The combination with an arch-axle and wheels, of brackets attached tosaid archaxle, a frame pivoted at its forward end to said brackets, aplow-beam connected with the arch-axle, and means mounted on the frameand connected with said arch-axle for raising and lowering the beam.

2. The combination with an arclraxle and carrying-wheels, of a frameconnected at its forward end with said axle, means for supporting therear end of the frame, a plowbeam connected with the arch-axle, abracket attached to the arch-axle, and means mounted on the frame andconnected with said bracket for raising and lowering the plow.

3. The combination with an arch-axle and carrying wheels, of a frameconnected at its forward end with the arch-axle, a. plowbeam connectedwith the arch-axle, a loop on the forward portion of the plow-beam, abail connected with the forward end of the frame and engaging said loop,and. means for supporting the rear end of said frame.

t. The combination with an arch-axle and carrying wheels, of a plow beamconnected with the U-shaped portion of the arch-axle, brackets attachedto the alining portions of said arch-axle, a loop secured to the forwardportion of the beam, a bail connected with said brackets and, engagingsaid loop, a frame connected at its forward end with said brackets, andmeans for supporting the rear end of said frame.

The combination with an arch-axle,

l carrying wheels, and a plow-beam connected i with said arch-axle, of aframe connected t at its forward end with the arch-axle, means i mountedon the frame and connected with 1 the arch-axle for raising and loweringthe y plow, a spring attached at one end to the 1 arch-axle and at theother end to the frame for assisting in raising the plow, and means ifor supporting the rear end of the frame. l G. The combination with anarch-axle and carrying wheels, of a frame supported at its y forward endby the arch-axle, a plow-beam connected with the arch-axle, a levermountt ed on the frame and connected with the archaxle for raising andlowering the plow, a bracket secured to the rcarend of the frame, anaxle having a mounting in said bracket, follower-wheels on said axle, anotched-arm secured to the upper end of said axle, a latch mounted onthe frame and engaging said notched-arm, bell-crank lever, a connectionbetween said bell-crank lever and said latch, and, means operated by thefirst mentioned lever to engage the bell-crank lever and move said latchto release the axle at the rear end of the same when said firstmentioned lever is operated to raise the plow.

7. The combination with an arch-axle and carrying wheels, of a framecomprising two members secured together at their rear ends and connectedat their forward ends with the a ch-axle at respective sides of the U-shaped intermediate portion thereof, a plow beam connected with thearch-axle, a bail connected with the forward end of said frame andhaving a sliding connection with the forward portion of the plow beam,and means mounted on the frame and connected with the arch-axle forraising and lowering the plow.

' In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
